    Echocardiographic Indices Compared with Galectin-3 and Pentraxin-3 in Stage C Heart Failure

    by Alexandru-Florinel Oancea, Paula Cristina Morariu, Maria Godun, Alexandru Jigoranu, Radu Stefan Miftode, Ovidiu Mitu, Paul Simion, Dragos Traian Marcu, Amin Bazyani, Antoniu Octavian Petriș, et al.

    Background/Objectives: We compared echocardiographic indices with galectin-3 and pentraxin-3 for discriminating established heart failure (HF). Methods: This exploratory cross-sectional secondary analysis included 131 coronary angiography patients: 69 with stage C HF and 62 without an established clinical HF syndrome. Patients with HF were clinically stable without symptoms at rest and were classified as New York Heart Association (NYHA) II or III at study evaluation. Tricuspid annular plane systolic excursion/pulmonary artery systolic pressure (TAPSE/PASP), the combined mitral Doppler index E/(Em × Sm), right ventricular systolic annular velocity, and both biomarkers were assessed using paired receiver operating characteristic comparisons and clinically adjusted logistic regression. Results: TAPSE/PASP had the highest numerical area under the curve (AUC 0.753; 95% confidence interval 0.671–0.835) and outperformed galectin-3 (AUC 0.500; Holm-adjusted p = 0.0012). Its AUC difference from pentraxin-3 was nonsignificant. E/(Em × Sm) and pentraxin-3 had AUCs of 0.654 and 0.631. TAPSE/PASP retained an association with HF in the joint adjusted model (odds ratio 0.55 per standard deviation; p = 0.0423); E/(Em × Sm) did not. Pentraxin-3 remained associated in its separate adjusted model (odds ratio 1.70; p = 0.0212). NYHA-class and ejection-fraction subgroup differences were nonsignificant after multiplicity correction. Conclusions: TAPSE/PASP discriminated established HF better than galectin-3 in this cohort. The separate pentraxin-3 association warrants further investigation of complementary inflammatory information. These exploratory findings, models, and derived thresholds require independent validation before clinical application.

    Serum and Salivary Amylase Variations During Exercise Testing in Athletes and Their Correlation with Cardiovascular Parameters—A Pilot Study

    by Cezar Honceriu, Alexandru Dan Costache, Beatrice Aurelia AbălașEi, Alin Ciobică, Alexandra MașTaleru, Andrei Drugescu, Diana Elena Cosău, Minerva Codruța Bădescu, Iulia Cristina Roca, Andreea Rotundu, et al.

    Background and Objectives: During intense bouts of physical activity, the body of athletes is subjected to stress and sometimes this can lead to adverse events such as injuries or more severe organ dysfunction, like sudden cardiac death. Several markers are being studied to properly assess the level of physical stress that exercises have on the body and one of them is amylase. Materials and Methods: We evaluated 19 licensed football players using basic cardiovascular procedures, i.e., resting 12-lead electrocardiogram (ECG) and trans-thoracic echocardiography (TTE) and performing a cardiopulmonary exercise testing (CPET). Resting (T0) serum and salivary amylase levels were measured, as were immediately post-effort (T1) serum values and 10 min (T2) and 30 min post-CPET (T3) salivary values. Results: Both serum and salivary levels showed correlations with several TTE and CPET parameters. Only T2 salivary amylase levels did not show any correlations with the other parameters, while also no correlations could be established between serum and salivary determinations. Conclusions: Serum and salivary amylase determinations show potential in athlete evaluation even from a cardiovascular risk standpoint since they displayed several correlations with both TTE and CPET parameters, but as part of a more complex protocol. Salivary determinations cannot fully substitute serum measurements. Further studies on larger groups are required.

    Exploratory Real-World Observations on Pulmonary Function Evolution, HRCT Patterns, and Antifibrotic Escalation in Systemic Sclerosis-Associated Interstitial Lung Disease Treated with Mycophenolate Mofetil

    by Diana Elena Cosău, Mihai Roca, Alexandru Dan Costache, Irina Iuliana Costache Enache, Ionela Lăcrămioara Șerban, Mara Russu, Vladia LăpușTe, Alexandra Lori Donica, Cristina Pomîrleanu, Codrina Ancuța

    Systemic sclerosis-associated interstitial lung disease (SSc-ILD) remains an important cause of morbidity and mortality in systemic sclerosis. Mycophenolate mofetil (MMF) is widely used as first-line immunosuppressive therapy; however, real-world descriptions of pulmonary functional and radiologic evolution during MMF therapy remain limited, particularly according to high-resolution computed tomography (HRCT) pattern. Objectives: To descriptively evaluate pulmonary function evolution, radiologic findings, and safety outcomes in patients with SSc-ILD treated with MMF in routine clinical practice, with exploratory analyses according to HRCT pattern and subsequent antifibrotic use. Materials and Methods: We conducted a retrospective single-center study including 20 patients with SSc-ILD treated with MMF. Clinical, functional (forced vital capacity [FVC]; diffusing capacity for carbon monoxide [DLCO]), and radiologic (HRCT Warrick score) parameters were assessed at baseline, 6 months, and 12 months. Patients were stratified according to nonspecific interstitial pneumonia (NSIP) and usual interstitial pneumonia (UIP) patterns. Statistical analyses were exploratory and descriptive. Results: Pulmonary function remained overall stable during follow-up under MMF therapy, while DLCO improvement was observed at 6 months and remained stable at 12 months. Radiologic progression appeared more limited in patients with NSIP pattern, whereas patients with UIP pattern generally exhibited more frequent radiologic progression during follow-up. Patients who subsequently received nintedanib generally presented with UIP-pattern disease, lower baseline DLCO values, and more advanced pulmonary involvement. MMF was generally well tolerated, with treatment discontinuation due to adverse events observed in a single patient. Conclusions: This small retrospective real-world case series describes pulmonary functional and radiologic evolution in patients with SSc-ILD treated with MMF in routine clinical practice. Overall functional stabilization was observed during follow-up, while radiologic progression was more frequently observed in patients with UIP-pattern disease and more advanced baseline pulmonary involvement. Because of the exploratory descriptive design and limited sample size, these observations should be interpreted cautiously and considered hypothesis-generating only. Further prospective studies with standardized radiologic assessment are required.

    Repurposing Coronary Risk Scores to Identify Increased Likelihood of Atrial Fibrillation in Chronic Coronary Syndrome

    by Alexandru-Florinel Oancea, Mathilde Leonard, Paula Cristina Morariu, Maria Godun, Alexandru Jigoranu, Ionela-Larisa Miftode, Radu Stefan Miftode, Aurelia Mihaela Nica, Alexandra Rotaru, Paul Simion, et al.

    Atrial fibrillation (AF) frequently coexists with chronic coronary syndrome (CCS), reflecting shared cardiovascular risk factors and structural remodeling pathways. Identifying CCS patients at increased likelihood of AF remains clinically relevant, particularly when arrhythmia is silent or paroxysmal. Background: We hypothesized that established clinical and angiographic risk scores used in CCS may capture cumulative cardiovascular burden and could therefore assist in AF risk stratification. The biomarker-based ABC-stroke score was incorporated as a biological reference framework reflecting myocardial stress and injury. Methods: This prospective, single-center proof-of-concept study included 131 consecutive patients undergoing invasive coronary angiography for suspected myocardial ischemia. Patients were classified according to rhythm status, irrespective of AF subtype. Coronary artery disease severity was quantified using the Gensini and SYNTAX (PCI and CABG) scores. Global cardiovascular risk was assessed using Framingham, ASCVD, SCORE2, and SCORE2-OP. Correlation analyses, ROC curves, and multivariable logistic regression were performed to evaluate associations between risk scores, coronary complexity, and AF. Results: Clinical and angiographic risk scores differed significantly according to rhythm status and AF phenotype. Patients with AF exhibited higher global cardiovascular risk and greater coronary anatomical complexity compared with those in sinus rhythm. SYNTAX PCI and SYNTAX CABG demonstrated moderate discriminative performance for AF detection (AUC 0.745 and 0.760, respectively), with SYNTAX CABG remaining independently associated with AF in multivariable analysis. Significant correlations were observed between traditional cardiovascular risk scores and SYNTAX-derived measures of coronary complexity, whereas correlations with the Gensini score were weaker. The ABC-stroke reference model showed a strong discriminative signal, consistent with its biological proximity to AF-related myocardial stress. Conclusions: Established clinical and angiographic risk scores used in CCS are associated with the presence and phenotype of AF. These findings suggest that routinely available coronary risk assessment tools may serve as practical instruments for identifying CCS patients at increased likelihood of AF, potentially facilitating targeted rhythm screening and earlier risk stratification.

    From Beat to Risk: How Heart Rate Variability Predicts Arrhythmias in Type 2 Diabetes

    by Amelian Madalin Bobu, Ștefania-Teodora Duca, Andrei Ionut Cucu, Diana Alina Avieriței, Cosmina-Georgiana Ponor, Maria-Ruxandra Cepoi, Sandu Cucută, Bianca-Ana Dmour, Claudia Florida Costea, Gina Botnariu, et al.

    Type 2 diabetes mellitus is associated with major cardiovascular complications, including cardiac autonomic neuropathy, which contributes to sympathetic–parasympathetic imbalance and increases susceptibility to arrhythmias and sudden cardiac death. Heart rate variability, assessed through R–R intervals on electrocardiography and 24 h Holter monitoring, represents a sensitive, non-invasive marker of autonomic dysfunction and arrhythmogenic risk. In patients with type 2 diabetes mellitus, chronic hyperglycaemia, oxidative stress, and metabolic inflammation lead to early impairment of the autonomic nervous system, manifested by consistent reductions in SDNN, RMSSD, pNN50, total power, and the high-frequency component, indicating diminished parasympathetic tone and sympathetic predominance. Nonlinear HRV indices demonstrate a loss of complexity and fractal organisation, providing additional prognostic value beyond conventional time- and frequency-domain analyses. Reduced HRV correlates with the severity of cardiac autonomic neuropathy, duration of diabetes, and poor glycaemic control, identifying patients with increased arrhythmogenic vulnerability. HRV analysis enables prediction of arrhythmic risk, facilitating the identification of high-risk individuals and guiding personalised interventions. The integration of HRV assessment into routine clinical practice may improve the early detection of subclinical autonomic neuropathy and optimise cardiovascular risk stratification and management in patients with type 2 diabetes mellitus.

    Assessment of Congestion in Heart Failure Using VExUS: Current Evidence, Limitations and Clinical Perspectives

    by Cosmina-Georgiana Ponor, Maria-Ruxandra Cepoi, Marilena Renata Spiridon, Ionuț Tudorancea, Amelian Mădălin Bobu, Minerva Codruta Badescu, Alexandru Dan Costache, Sandu Cucută, Irina-Iuliana Costache-Enache

    Background: Systemic venous congestion is a key driver of organ dysfunction in heart failure (HF), yet accurate non-invasive quantification remains challenging. Recognizing residual congestion is critical, since it predicts HF readmissions and mortality. Traditional assessments (physical exam, jugular venous pressure, inferior vena cava [IVC] size) are imprecise. The Venous Excess Ultrasound Score (VExUS) is a semi-quantitative point-of-care ultrasound (POCUS) protocol that integrates IVC diameter with Doppler flow patterns in the hepatic, portal and intrarenal veins to grade systemic venous overload. Methods: We conducted a narrative review of literature (2018–2025) regarding the usefulness of VExUS in HF, covering congestion pathophysiology, clinical evidence (hemodynamic correlations, organ dysfunction, outcomes), potential applications, integration with lung ultrasound, echocardiography and biomarkers, limitations of its assessment and future directions. Results and Discussions: In HF, elevated right atrial pressure causes venous congestion. VExUS integrates IVC diameter with Doppler waveforms of hepatic, portal, and intrarenal veins to grade congestion. Emerging evidence shows higher VExUS grades correlate with elevated filling pressures, renal dysfunction, and worse outcomes. Its use may guide diuretic therapy, aid discharge planning, and monitor outpatient congestion, especially when combined with lung ultrasound and biomarkers. However, VExUS has limitations: it is technical and operator-dependent. Importantly, large trials validating VExUS-guided management are lacking. Future directions include AI-driven automation of Doppler analysis and integration with multimodal congestion monitoring to provide a comprehensive congestion assessment. Conclusions: VExUS is a promising noninvasive tool for quantifying congestion in HF. Higher grades are associated with organ dysfunction and poor prognosis. Incorporating this technique into HF care may improve congestion-guided therapy, but large-scale validation is required before routine use.

    Integrating GDF-15 into Multimarker Assessment of Acute Heart Failure: Diagnostic and Prognostic Implications

    by Bianca-Ana Dmour, Minerva Codruta Badescu, Daniela Constantinescu, Cristina Tuchiluș, Corina Maria Cianga, Gina Eosefina Botnariu, Ionela Lăcrămioara Șerban, Awad Dmour, Amelian Madalin Bobu, Alexandru Dan Costache, et al.

    Acute heart failure (AHF) is a leading cause of hospitalization and mortality worldwide. Despite advances in biomarker-based evaluation, accurate diagnostic and prognostic stratification remains challenging in everyday clinical practice. Growth differentiation factor-15 (GDF-15) has emerged as a biomarker associated with advanced disease profiles, poor outcomes and complex underlying pathophysiological processes in heart failure (HF). This study aimed to investigate the diagnostic and prognostic value of GDF-15 in the acute setting and to evaluate its incremental role within multimarker assessment strategies. In this prospective cohort study, 60 patients hospitalized with AHF and 42 control subjects were enrolled. Circulating levels of GDF-15, N-terminal pro–B-type natriuretic peptide (NT-proBNP), and high-sensitivity cardiac troponin I (hs-cTnI) were measured at admission. Diagnostic performance was assessed using receiver operating characteristic (ROC) analysis and multivariable logistic regression. Prognostic value was evaluated for in-hospital, short-term, and one-year mortality, including multimarker models. GDF-15 levels were significantly elevated in AHF and demonstrated a favorable diagnostic profile, with high specificity and acceptable sensitivity. When integrated into multivariable diagnostic models, GDF-15 added significant value beyond established cardiac biomarkers. For prognosis, standalone biomarkers showed limited long-term discrimination, whereas multimarker approaches incorporating GDF-15 improved short-term mortality prediction and enhanced one-year risk stratification in patients with markedly elevated NT-proBNP levels. GDF-15 provides independent diagnostic and prognostic information in AHF and enhances multimarker strategies for comprehensive patient assessment, supporting its integration as a complementary biomarker in contemporary AHF evaluation.

    Coronary Artery Spasm in Patients with Type 2 Diabetes Mellitus

    by Theodor Iulian Matei, Minerva Codruta Badescu, Alexandru Dan Costache, Ionuț Tudorancea, Ionela Lăcrămioara Șerban, Sandu Cucută, Bianca-Ana Dmour, Raluca Daria Mitea, Radu-George Ciorap, Ciprian Rezus, et al.

    Cardiovascular disease and diabetes mellitus have now reached pandemic proportions, and their association has become very common. Some patients with coronary artery disease and diabetes remain symptomatic, with chest pain present despite the implementation of evidence-based medical treatment and maximal therapy. A hypothesis increasingly confirmed in clinical practice is that epicardial or microvascular spasm, or both, are frequently responsible for the lack of symptom control or for the occurrence of major adverse cardiovascular events. Our review provides the most up-to-date and in-depth analysis of the available literature to provide solid knowledge about coronary spasm in diabetes patients. We have deepened the substrate of coronary spasm in relation to the multiple and complex structural and functional abnormalities produced by chronic hyperglycemia, with the ultimate goal of allowing optimization of treatment and improving patient outcomes.

    Beyond Coronary Risk: Clinical Scores as Predictors of Atrial Fibrillation in Chronic Coronary Syndrome

    by Alexandru- Florinel Oancea, Mathilde Leonard, Paula Cristina Morariu, Maria Godun, Alexandru Jigoranu, Ionela-Larisa Miftode, Radu Stefan Miftode, Alexandra Rotaru, Paul Simion, Diana-Gabriela Iosep, et al.

    Atrial fibrillation frequently coexists with chronic coronary syndrome, sharing common cardiovascular risk factors and pathophysiological mechanisms. Identifying patients with chronic coronary syndrome at increased likelihood of atrial fibrillation remains clinically relevant, particularly in the absence of overt arrhythmia. Clinical and angiographic risk scores routinely used in coronary artery disease may capture cumulative cardiovascular and structural burden and could therefore assist in atrial fibrillation risk stratification. The ABC score provides a more accurate and individualized assessment of risk than traditional clinical scores in patients with AF. Materials and Methods: This prospective, single-center, proof-of-concept study included 131 consecutive patients undergoing invasive coronary angiography for suspected coronary ischemia were enrolled. Patients with and without atrial fibrillation were included, irrespective of arrhythmia subtype. Coronary artery disease severity was assessed using the Gensini and SYNTAX (PCI and CABG) scores. Global cardiovascular risk was evaluated using established clinical scores, including Framingham, ASCVD, SCORE2, and SCORE2-OP. Comparisons were performed between patients in sinus rhythm and those with different atrial fibrillation phenotypes. Correlation analyses, receiver operating characteristic curves, and multivariate logistic regression were applied to evaluate the association between risk scores, coronary disease severity, and atrial fibrillation. Results: Clinical and angiographic risk scores differed significantly according to rhythm status and atrial fibrillation subtype. Patients with atrial fibrillation exhibited higher values of global cardiovascular risk scores and greater coronary anatomical complexity compared with patients in sinus rhythm. The ABC score demonstrated the strongest discriminative performance for atrial fibrillation detection (AUC 0.908), followed by SYNTAX PCI and SYNTAX CABG. In multivariate analysis, the ABC score and SYNTAX CABG emerged as independent predictors of atrial fibrillation. Significant correlations were observed between traditional cardiovascular risk scores and SYNTAX-derived measures of coronary complexity, whereas correlations with the Gensini score were weaker. Established clinical and angiographic risk scores used in chronic coronary syndrome are associated with the presence and phenotype of atrial fibrillation. These findings support the potential role of routinely available risk scores as practical tools for identifying chronic coronary syndrome patients at increased likelihood of atrial fibrillation, facilitating targeted rhythm screening and early risk stratification.

    Diagnostic and Severity Assessment of Coronary Artery Disease Using ApoB/ApoA-I Ratio: Insights from a Statin-Treated Eastern European Cohort

    by Raul-Alexandru Jigoranu, Ovidiu Mitu, Alexandru Florinel Oancea, Radu-Stefan Miftode, Ana Maria Buburuz, Amin Bazyani, Radu-Sebastian Gavril, Theodor-Constantin Stamate, Cristina Andreea Adam, Ionela-Larisa Miftode, et al.

    Background and Objectives: Atherosclerosis continues to be a major determinant of the global health burden, with ischemic heart disease representing one of the leading causes of morbidity and mortality worldwide. Although cardiovascular (CV) prevention strategies focus on pro-atherogenic lipoproteins, such as LDL-C, non-HDL-C, and apoB, the balance between atherogenic and anti-atherogenic lipoproteins may better reflect the overall atherogenic burden. Apolipoprotein B (apoB) reflects the total number of circulating atherogenic particles, whereas apolipoprotein A-I (apoA) is the main protein component of HDL, the major anti-atherogenic lipoprotein. Integrating these two parameters into the apoB/apoA ratio results in a composite biomarker that reflects this balance. In this study, we aimed to evaluate whether the apoB/apoA ratio can predict the presence and the severity of coronary artery disease (CAD) in a cohort from an Eastern European hospital, under moderate-intensity statin treatment. Additionally, we assessed whether lipoprotein(a) [Lp(a)] provides any additional diagnostic value. Materials and Methods: We consecutively enrolled 121 statin-treated patients, who presented for elective invasive coronary angiography. Patients with history of coronary revascularization or acute coronary syndrome were excluded. The study cohort was further divided into two groups, according to the severity of coronary stenosis: 69 patients with non-significant CAD (N-CAD) and 52 patients with hemodynamically significant CAD (S-CAD). Apolipoprotein B, apolipoprotein A-I, and lipoprotein(a) were measured using a standardized immunoturbidimetric assay, at the moment of enrollment. The severity of coronary stenosis was measured using Quantitative Coronary Analysis (QCA) software and the total coronary atherosclerotic burden of each patient was quantified using the Gensini score. Results: The apoB/apoA ratio was significantly higher in the S-CAD groups, compared with N-CAD patients (0.53 ± 0.16 vs. 0.73 ± 0.18). Furthermore, in the apoB/apoA-based analysis, the Gensini score increased progressively across the three tertiles (8.55 ± 19.60 vs. 14.57 ± 21.65 vs. 29.8 ± 27.78, p = 0.000) and so did the percentage of patients with three-vessel disease (5% vs. 19.5% vs. 32.5%, p = 0.000) and left main disease (5% vs. 7.3% vs. 20%, p = 0.031). The apoB/apoA ratio showed a significant correlation with the severity of CAD, as expressed by the Gensini score (r = 0.513, p < 0.001, 95% CI: 0.357–0.641). The association between apoB/apoA ratio and the presence and severity of CAD expanded beyond group comparison. In the logistic regression, this biomarker proved to be a valuable predictor for S-CAD (per SD increase: OR 2.509, 95% CI: 1.441–4.369, p = 0.001), three-vessel disease (per SD increase: OR 2.339, 95% CI: 1.427–3.892, p = 0.001), and left main disease (per SD increase: OR 2.771, 95% CI: 1.489–5.156, p = 0.001). The apoB/apoA ratio remained significant after adjusting for other CV risk factors and independent to LDL-C, as shown by the analysis that we performed among the lowest LDL-C tertile patients. Participants with S-CAD showed higher concentrations of Lp(a). However, adding this lipoprotein to the multivariate analysis, resulted only in a marginal improvement in the predictive power. Conclusions: The ApoB/apoA ratio emerged as an independent predictor for hemodynamically significant coronary stenosis and for CAD severity. Additionally, higher apoB/apoA values were associated with anatomical high-risk features, such as three-vessel disease or left main disease. In contrast, Lp(a) did not provide a substantial increase in the predictive power of multivariate models in this stable CAD cohort.
